“…Working in modified light environments, Chagas et al (2013) observed that, in Japanes pepper mint plants, the production of essential oil was more influenced by intensity than by quality of the light. While also l studying light environments, Oliveira et al (2016), found that the highest oil contents extracted from oregano plants were found in those grown under full sun. Changes in the essential oil content of Lippia sidoides were found by Souza et al (2007) when these plants were cultivated under different percentages (75, 50 and 25%) of shading.…”

Medicinal plants have great potential for the production of phytocompounds, which are used for various purposes, mainly in drugs and cosmetics. The aim of this study was to evaluate the essential oil from Lippia alba cultivated with ammonium (NH4+) and nitrate (NO3-) under light environments. The plants were subjected to five ratios of NH4+: NO3- with nutritious solutions and four light environments (red, aluminet and black mesh, and full sun). The experiment design was entirely randomized with a 5 × 4 interaction and five repetitions per treatment, totaling 100 experiment units. The seedlings were transplanted to 6 dm3 plastic pots containing a mixture of washed sand + vermiculite at a ratio of 2:1. At 120 days after application of the treatments, the following parameters were evaluated: yield, content and composition of essential oil. The extraction was performed with the hydrodistillation method using drag of steam for a period of 2 hours. Nine compounds were found in the essential oil, of which neral and geranial represented 90% of the blend. Carvone was only found in the treatment with plants grown under the red mesh and with the 50:50 ratio of ammonium and nitrate.

The objective of this study was to evaluate the effect of ChromatiNet on vegetative growth, total antioxidant capacity, phenolic and essential oils (EOs) composition of Lippia gracilis. The plants were cultivated under full sunlight, black, blue and red ChromatiNet. The flavonoid content and antioxidant capacity were quantified spectrophotometrically. The C‐glycosylflavone isomers (orientin and isoorientin) were isolated and identified by conventional spectroscopic techniques and measured using high‐performance liquid chromatography‐diode array detection. The EO was analysed by gas chromatography and gas chromatography‐mass spectrometry. Environment influenced growth, total antioxidant capacity and phytochemical levels. Shoot dry weight, thymol, carvacrol and (E)‐caryophyllene were favoured under red and black ChromatiNet. Root growth, EOs, caryophyllene oxide, p‐cymene, flavonoids, orientin and isoorientin were favoured in sunlight. Growth and accumulation of EOs, flavonoids and photosynthetic pigments increased under blue ChromatiNet. Therefore, Lippia gracilis plants have plasticity related to the spectral quality of light and it cultivate depends of the phytochemicals of interest.
